After Mercedes, even the Renault Group decides to focus on axial flux electric motors for the future. The Losanga carmaker has in fact acquired a 21% stake in Whylot, a French company that is developing an electric motor of this type. More and more car manufacturers are deciding to invest in axial flux electric motors, a promising technology that promises one higher power density per kilogram of weight: Renault is convinced that an engine of this type can guarantee a saving of 2.5 grams of CO2 per kg in a hybrid application.
Recall that Renault had previously announced a partnership with Whylot, without ever going to affect its participation. The first details of the agreement ensure that the two companies plan to develop and commercialize an axial flux motor for all-electric and hybrid powertrains. starting in 2025. As Autonews rightly points out, the electric motors used in vehicles today are radial flux, which means that the direction of magnetic fluxes is perpendicular to the axis of rotation. In an axial flux motor, however, the fluxes are parallel, which materializes in a shorter magnetic path, smaller overall dimensions and greater efficiency. This type of electric motor could be useful for supercar manufacturers of the caliber of Ferrari, which Ferrari, which turned to YASA to build radial-flow engines for its hybrid SF90 Stradale.
“We are delighted to take a further step in our relationship with Whylot, a promising start-up specializing in design and development of high-tech electric motors – declared Philippe Brunet, Director of Thermal and Electric Powertrains of the Alliance – This partnership, coupled with the acquisition of a stake in the company capital, is further demonstration of our strong French roots and the Renault Group’s industrial roots in France, with the will to produce popular, affordable and profitable electric and electrified vehicles there. “. As mentioned, last week too Mercedes has announced its intention to focus on axial flux electric motors: the carmaker of the Star has decided that it will use its most historic plant, the one in Berlin, to produce its first “in-house” axial flux electric motor.
